To add users, select add. GFI MailSecurity will automatically list all the
users listed in Active Directory. If you do not have Active Directory, all
known/imported SMTP addresses will be listed.
You can then select to which users to apply the rule. Alternatively you
can select the users to which the rule should not apply! You can also
apply the rule to one or more mail enabled public folders. When you
are ready specifying to which users the rule will apply, click OK to
save the rule.
Renaming the rule
After you have created and saved the rule, you can rename it. To do
this, simply right click on the rule and select `rename'.
Creating an attachment checking rule
An attachment checking rule allows you to block attachments of a
certain type. The attachment checking rule differs from the content
checking rule in that it only checks for a type of attachment. The
content checking rule checks attachments also, but only for words
contained in them.
If running in Exchange VSAPI mode:
Be careful when applying
attachment rules! Some MAPI applications running on Exchange
might be using vbs or exe files. You need to ensure that if this is the
case, you don't apply rules to quarantine exe or vbs files to mailboxes
used by those applications.
To create an attachment checking rule:
1. Highlight the Attachment checking node in the GFI MailSecurity
configuration. Right click and select New> Attachment checking rule.
2. A new rule will be created in the right pane. Double click on this
rule. A tabbed dialog will appear.
